I’d explore the lubrication techniques first.

I know where to cut because I can see them by taking down the basement wall. I already had a good idea based on the location of the valves. Now when I say cut a hole, I mean one big enough to work in, maybe 4 or 5 ft wide, and a similar length front to back. As long as the flap is to the front it can't blow open and the scrim tape I use is super sticky and reinforced, it is what the RV shops use for repairs. All this assumes it is a valve replacement, if the tank needs to come out then I would have a dealer do it.
